## Overview

STEP RAILWAY is a train-ticket booking web app. Users search stations and departures, choose a train, select seats and enter passenger details to register a booking; they can also check or cancel tickets and log in or register. The Angular pages call a shared railway service for API operations, with separate translation and theme services supporting the interface. The README documents the major API capabilities. Some connections are based on indexed imports or README documentation rather than inspected implementation; those limits are reflected in the edges.

Main entry points: [`src/app/services/railway.service.ts`](https://github.com/h5nz9y227w-web/angulat-railway-project/blob/main/src/app/services/railway.service.ts) (Railway API Client), [`src/app/booking/booking.component.ts`](https://github.com/h5nz9y227w-web/angulat-railway-project/blob/main/src/app/booking/booking.component.ts) (Seat Booking), [`src/app/home/home.component.ts`](https://github.com/h5nz9y227w-web/angulat-railway-project/blob/main/src/app/home/home.component.ts) (Search Home), [`src/app/trains/trains.component.ts`](https://github.com/h5nz9y227w-web/angulat-railway-project/blob/main/src/app/trains/trains.component.ts) (Train Results)
